Cloud-based Solutions

• A Cloud-based solution (cloud) refers to an
  on-demand delivery of computing resources that
  can be accessed through the Internet and through
  the shared cloud computing infrastructure of
  another provider. It provides access to many
  resources (storage space, networks, software and
  applications and other on-demand services).
• Cloud-based solutions benefits include increased
  scalability and functionality as well as a
  reduction in cost that has to do with computer
  infrastructure, maintenance and in keeping and
  training an in-house IT staff. It helps companies
  to focus on their core business.
• There are 3 categories of Cloud pricing models,
  which are usually offered as a pay-as-you-go
  subscription. These are-
• Servers in the cloud
• Applications/sites in the cloud
• Storage in the cloud

Cloud
Deployment Models

• YELLOW
• Cloud deployment models refer to the types of
  cloud environment, which can be public, private
  or hybrid clouds. Businesses can opt for any of
  these, depending on their particular
  requirements. These will be discussed in more
  detail in the following slides.
• To digress, the term cloud brings to mind cloud
  hosting, which is one of the types of web hosting
  service and is provided by web hosting companies.
  The other types of hosting services can be
  shared, dedicated, VPS, reseller, WordPress etc.
  The best companies in the hosting business are
  often referred to as the Best Website Hosting
  Company, the Best Windows Hosting Company or
  as the Top Cloud Hosting Company.

Public
Cloud

• An outsourced cloud provider owns a public cloud.
  It can be accessed by many businesses via the
  Internet. It helps organizations save money with
  regard to IT operational costs, by providing the
  necessary services and infrastructure. In it, the
  cloud provider is responsible for resources
  creation and maintenance. It is usually the small
  and medium-sized businesses that have budget
  constraints which find public clouds an ideal
  option.

Advantages and Disadvantages of Public
Cloud

• YELLOW
• Advantages
• Cost-effective
• Extremely reliable
• Easy to manage
• Easy to scale
• Geographical restrictions dont exist
• Disadvantage
• It isnt the safest option with regard to data
  that is sensitive

• Whoa! Thats a big number, arent you proud?

Private Cloud
A private cloud offers services to a selected
group of users rather than to the general public,
either over the Internet or over an internal
network that is private. This type of cloud
deployment model can be hosted externally with
regard to the business using it, or it can be
managed in-house. A more controlled environment
is offered by it. In it the access to IT
resources is more centralized. Private clouds
offer more security and privacy. Despite being
expensive, it provides greater autonomy with
regard to customizing storage as well as
networking, to suit the IT requirements of a
business. Since it is an organizations IT staff
that is responsible for managing a private cloud,
it calls for the same staffing as well as
expenses for maintenance and management that is
required by a data center.

Hybrid Cloud

• YELLOW
• A hybrid cloud deployment model provides the
  benefits of both, a public and a private cloud.
  In it a private cloud is combined with one or
  more public cloud services by using proprietary
  software that enables communication among
  distinct services. Greater flexibility is gained
  by businesses when they use a hybrid cloud
  strategy. This is accomplished by shifting
  workloads among cloud solutions depending on the
  fluctuations in costs and requirements.
• Hybrid cloud services enable businesses to have
  more control over their private data. A business
  can store its sensitive data on a private cloud
  and utilize the powerful computational resources
  of a public cloud. In a hybrid cloud, admins
  dont need to manage each cloud environment
  separately which is the case in a multi-cloud
  environment.

Advantages and Disadvantages of Hybrid
Cloud

• YELLOW
• Advantages
• Extremely flexible and scalable
• More secure
• Cost-effective
• Disadvantage
• Conflicted communication at network level

Cloud Service Models

• YELLOW
• Cloud service models are of three types, which
  are distinctly different from each other, but
  these are capable of interacting with each other
  to form a comprehensive cloud service model.
  These three types of cloud service models are
  mentioned below.
• Infrastructure as a Service (IaaS)
• Platform as a Service (PaaS)
• Software as a Service (SaaS)

13

Infrastructure as Service
(IaaS)

• YELLOW
• IaaS is the most common type of cloud service
  model. It provides a fundamental infrastructure
  that includes data storage drives, virtual
  servers, operating systems and network. It offers
  the reliability, scalability and the flexibility
  that a cloud environment is known to provide to
  businesses. Moreover, it eliminates the need to
  maintain hardware in a companys office. It is an
  outsourced service that is available as a
  private, public or as a hybrid infrastructure.
• It is an ideal option for small and medium-sized
  organizations that are looking for an IT solution
  which supports their business and is
  cost-effective.

14

Platform-as-a-Service (PaaS)

• YELLOW
• PaaS involves deployment of the infrastructure
  and software framework by the cloud computing
  providers and lets businesses develop as well as
  run their own applications. PaaS aids in creating
  web applications easily and quickly. Moreover,
  the service is sufficiently powerful and flexible
  to support these.
• These scalable solutions are ideal for situations
  where multiple developers are working on one
  project as well as for such situations which
  require an existing data source to be leveraged.

15

Software as a Service
(SaaS)

• YELLOW
• In SaaS software is deployed to various
  businesses over the Internet. It serves as an
  important tool for applications that require a
  substantial amount of web or mobile access and is
  an ideal option for short-term projects. Since
  SaaS is managed from a central location,
  businesses dont need to worry about its
  maintenance.
